Good suggestion by Susan. For some instant information look online for a map showing the constant wind
patterns called the trade
winds. In short there are four, large circular wind
patterns, north and south Atlantic and Pacific. Each circular pattern is a circular movement of winds with the current following. Looking at the north Atlantic circulation winds come from roughly southern Spain
towards the Caribbean
then from NE USA back towards Europe
So globally there are winds from the east on the north and south sides of the equator and winds from the west as you move away from the equator.
Any long ocean voyages are best done following these routes, otherwise you are beating your head
against a wall.
